How to run Prime95 and how long does it take?

I've run RAM tests and had 8 passes. In fact, my RAM is relatively new (bought in 2013) and I think it should not have any problems.

However, my whole system (windows 7) getting OBVIOUS lag and slow even after clean installation. I don't run any Photoshop or any video editing and I don't install any games which may require a high performance PC. Most of the time I use computer to download videos or view documents or the most 'extreme' case is to watch youtube videos.

My CPU is intel i5 2400 bought in mid 2011. I want to test if it has any problems. I don't know anything about overclocking and I don't do any overclocking.

I've downloaded and extracted Prime95, and I've also registered an ID on their website.

I'd like to know what's next. It looks quite complicated for me. How to start testing my CPU with Prime95? Is there any simpler step-by-step routine for me?

Thank You very much!
 
it sounds like you may have a mechanical hard drive that is taking its last breathes.... i recommend a system backup immediately. then, you may replace it or if u want to try to make it last wait until it dies. but, make sure you keep a backup copy of everything u do that way u dont lose any sensitive data.

other than that, of course it may be something else, but if you're lagging just doing every day things like browsing and things that's most likely going to be the problem.
 
I agree with the failing hdd diagnosis. Is there any unusual noise coming from the machine? Its typical for a failing hdd to cause the system to hang for split seconds or longer as the system cant retrieve the data from it correctly.
 
When you start Prime95 it will ask if you want to join something or just stress testing. Select just stress testing and run the default which is called blend.

However I don't think you'll find out anything by doing Prime, probably a different issue.
